1965 Coupe

Discussion Starter · May 17, 2015

I have a 289 4bbl that runs hot, replaced the thermostat, new sending unit, the radiator is 3rows, has new shroud. After replacing the sending unit the gauge stays within range, but when idling the gauge creeps toward the high range anything else that may help
Thanks:|,

As Rex said.
I would remove the thermostat all together first and see if it makes a difference on idle or running.
If it keeps cool on both runs then you need to get a thermostat that opens earlier.
